Does the earth have an unlimited supply of magma?

Geography
1 answer:
Nat2105 [25]3 years ago
5 0

Answer:

No

Explanation:

The magma supply of the Earth is not unlimited, but instead it has a fairly constant volume. On the other hand, the magma is not spending itself even though it constantly comes out on the surface of the Earth. The reason for that is that the magma that comes out on the surface, is actually replaced by newly formed magma. The newly formed magma is actually from the crust of the tectonic plates that are subducting. As the plates are subducting, they reach the mantle layer where the temperature and pressure are very high, so they melt the crust. The molten crust is becoming the new magma that replaces the one that is pushed toward the surface. This is a cycle that constantly goes on, so even though the magma is not endless, it manages to circle through the top two layers and replenish itself.

A vocabulary in context exercise in which students match words to definitions describing elliptical planetary orbits, applying i
Natali5045456 [20]

Answer:

1. Focus

2. Aphelion

3. Ellipse

4. Semimajor axis

5. Perihelion

6. Eccentricity

Explanation:

In Kepler's first law of planetary motion, he says that planets orbit around the sun, not in perfect circles, but in ellipses (3.) the Earth also orbits the sun in this shape. The shape of the ellipse is determined by two focii. The closer these two points are to each other, the more the ellipse will resemble a circle.

The moon for example, orbits around the Earth. The moon is not always at the same distance from the Earth in all points of the orbit. So the shape is an ellipse, which is made with Earth as one of its focus(1.).

Eccentricity(6.) describes the flatness the orbit is, or how elliptical the orbit is. Remember Kepler's first law, he says that planets move in elliptical orbits and not perfect circles. So it is simply how different from a perfect circle an orbit is. Pluto is known to have a large eccentricity.

Because of the shape of an ellipse, there are going to be points where a planet is closest to the sun and where a planet is farthest from the sun. This is where Kepler's 2nd law of planetary motion comes in. When the planet is closest to the sun, this is called the perihelion (5.) where a planet would be traveling the fastest at this point of the orbit. When the planet is at its farthest point from the sun, this is called the aphelion (2.) where a planet would be traveling the slowest.

The third law of Kepler describes the relationship between the period and the average distance of the sun. The semimajor axis(4.) is the average distance of the planet object from the sun and is measured in Astonomical units (AU). The period is measured in years.

An airplane takes off from a location at 17°S
Lilit [14]

The plane would reach a latitude of 38°N.

When it comes to lines of latitude, the Equator is 0°. Locations south of the equator increase from 0° as you go further South and those north increase from 0° as you go North.

If you therefore go from 17°S northward, the degrees of latitude will keep decreasing till you get to 0° and then start increasing as you go North.

The new location in this case will therefore be North:

= 55 - 17

= 38 °N

In conclusion, the plane will keep going North until it passes the Equator at 0° then it will keep going North till it gets to 38°N.
